Collectd df 🔗

Description 🔗

The Splunk Distribution of OpenTelemetry Collector provides this integration as the collectd/df monitor type for the Smart Agent Receiver.

Use this integration to track free disk space on the host using the collectd df plugin.

This monitor is available on Linux. Note a file system must be mounted in the same file system namespace that the agent is running in for this monitor to be able to collect statistics about that file system. This might be an issue when running the agent in a container.

Benefits 🔗

After you configure the integration, you can access these features:

  • View metrics. You can create your own custom dashboards, and most monitors provide built-in dashboards as well. For information about dashboards, see View dashboards in Observability Cloud.

  • View a data-driven visualization of the physical servers, virtual machines, AWS instances, and other resources in your environment that are visible to Infrastructure Monitoring. For information about navigators, see Splunk Infrastructure Monitoring navigators.

  • Access the Metric Finder and search for metrics sent by the monitor. For information, see Use the Metric Finder.
